Dexter

Based on novels by author Jeff Lindsay, Dexter follows the life of Dexter Morgan (Michael C. Hall), a charismatic blood spatter analyst who works in the forensics at the Miami Metro Police Department. On the outside, Dexter seems like the perfect guy -- he has a sister, Debra (Jennifer Carpenter), that adores him and a steady girlfriend, Rita (Julie Benz), with two kids that look up to him. However, what they don't know is that Dexter moonlights as a serial killer, only he isn't your typical killer. Basing his life on the teachings of his foster father, Dexter only kills people who truly deserve it: he ensures that those who got away with horrible crimes will never kill again.

In all fairness, dexter is not what it used to be, + if they followed the plot by the book it would have been so much interesting. I LOVED season #1, but hated everything since. The quality of the show is drastically declining with each season, they should really just end it. It's all the same, each season has the same structure. Someone new comes into Dexter's life and they do some killing together or discovering who he is and then in the season finale that person dies or moves out of his life. Boring, predictable.
